The total change from the beginning of the day to the end of the day is 4 29/ 122
<h3>What is rate of change?</h3>
A rate of change is simply a rate that describes how one quantity changes in relation to another quantity.
If a is the independent variable and b is the dependent variable, then:
Rate of change = change in b/change in a
We have that;
- Beginning of the day = 30 1/ 2 = 61/ 2 points
- End of the day = 129 1/4 = 517/ 4 points
Total rate of change = 517/ 4 ÷ 61/ 2
= 517/ 4 × 2/ 61
= 517/ 2 × 1/ 61
= 517/ 122
= 4 29/ 122
Thus, the total change from the beginning of the day to the end of the day is 4 29/ 122

Simple...
this would be a deci- meter,gram, etc
DECI being the prefix...and thus, your answer.
Answer:
The answer would be the purple line
and if I am wrong I think it is the red line
Step-by-step explanation:
Because our slope is -2 and the point is (-1,2)
the equation of the graphed line would be which is a linear equation
and the formula for the linear equation is
where m is the slope and b is the y-intercept and because we don't have a y-intercept the equation will look like y=-2x
Answer:
$33
Step-by-step explanation:
60x/100 = 20
Cross multiplying 100 and 20
60x= 2000
Make x subject of formula
X = 2000/60 = 33
Hence original price is $33
To divide these complex numbers you have to multiply by the conjugate of the denominator. That will look like this:
. Multiply straight across the top and straight across the bottom to get
. In the denominator, the 12i and -12i cancel each other out, which is nice. Now, in both the numerator and the denominator we have an i-squared. i-squared is equal to -1, so we will make that substitution in our solution:
. Doing the math on that we have
. We can simplify that as well as write it in standard form:
. Now we will get it into legit standard form, separating the real part of the complex number from the imaginary part.
. That can be reduced to its final answer of
. There you go!
